Metric Definition:

Litter Cover (%)

Benchmark Definition:

Upper detrimental threshold for litter cover due to increased fire hazard and suppression of native seedling germination in Arid Karstic Woodlands & Shrublands under Urban & Developed Use.

Justification:

Excessive litter accumulation (>60-70% cover) increases fire risk and suppresses native plant recruitment.
